Public Enemy’s Chuck D on Rhymesayers, racism and his legacy.

More than any other act, they gave hip-hop its social conscience -- the Bob Dylans of the rap world, if you will. They also had a big hand in rock fans taking rap music seriously. And they scared a lot of people.

When you remember all those facets of Chuck D and Public Enemy, it's no surprise that the pioneering New York rap troupe found no place for themselves in today's corporate-run, fluff-catering, mind-numbing mainstream hip-hop industry. It might come as a surprise, though, that these giants of rap looked to little old Minneapolis for some guidance on how to reinvent themselves.

"Honestly, Rhymesayers was one of the two main outfits we looked at in figuring out how to move forward," Chuck D said, with no prompting, about Minnesota's independent hip-hop mini-empire. "They set up a real good prototype for the rest of us and showed us how to do it."

That was just one of many bombs he dropped in a phone interview the day after Thanksgiving, when he started hyping the Hip-Hop Gods Tour coming to First Avenue on Thursday.

An all-star revue of sorts featuring Public Enemy and eight other rap acts that date back to the '80s -- including Monie Love, the X-Clan and Schoolly D -- Hip-Hop Gods is an extension of HipHopGods.Rapstation.com, one of several new websites that Chuck is involved in to give veteran hip-hop artists a platform to create and promote new music. Another of those sites, the distribution aggregator SpitDigital.com, is how PE released two new albums over the past four months.

These new-era platforms seem ironically timed to the other big news about Public Enemy: Chuck and his cronies are on the ballot for the Rock and Roll Hall of Fame, 25 years after the release of their debut album "Yo! Bum Rush the Show."

Even more than N.W.A. (also on the ballot), they seem like a shoo-in to be the fourth rap act to hit the hall, after Run-DMC, Grandmaster Flash & the Furious Five and the Beastie Boys, who were inducted by Chuck himself at last year's ceremony.

The rapper pointed to some of the hall's biggest names for what he said is "racist treatment of our legacies by the music industry." (Another bomb!)

"I think it's time for classic hip-hop to start getting treated more like classic rock," said the real-life Carlton Ridenhour, now 52. "There are too many radio stations to count still playing the Beatles and the Stones and Led Zeppelin, but there aren't any still playing Run-DMC and LL Cool J and Public Enemy."

Pointing to the parent companies of BET, MTV and many FM stations, he added, "We clearly can't rely on Clear Channel and Viacom -- who have way too much power over the modern rap world -- to keep our legacies relevant, or to lend any support to new music we are creating.

"I think we're as classic as Magic Johnson and Kareem Abdul-Jabbar," he concluded with a laugh. (Coincidentally, he stars with Abdul-Jabbar in a new episode of the Sundance Channel's "Iconoclast" series.)

Most hip-hop fans would agree with Chuck's assessment of Public Enemy, which he created with high-wire sidekick Flavor Flav while they were attending Adelphi University on Long Island in New York. After joining Run-DMC and the Beasties on Rick Rubin's fledgling Def Jam label to release "Yo! Bum Rush the Show," the group quickly put out two more incendiary and revered albums, "It Takes a Nation of Millions to Hold Us Back" and "Fear of a Black Planet."

Controversy came hand in hand with success. With its militaristic stage shows (guns included), radical politics and blunt deliveries, PE struck a combative stance epitomized in its anthem "Fight the Power" -- a song that played a pivotal role in "Do the Right Thing," Spike Lee's Oscar-nominated 1989 drama about the racial divide.

"None of it was ever contrived in any way, or done just for the sake of stirring up controversy and getting attention," Chuck recalled. With a slight laugh, he added, "You gotta remember: In the Reagan and first Bush era, any black person who raised their voice was considered controversial. So it really wasn't hard to get that kind of attention."

He addressed one specific controversy circa 1989, when one of the group's three DJ/producers, Professor Griff, was accused of making anti-Semitic statements while discussing turmoil in the Middle East. Griff is the only original member still active in PE's production crew.

"Originally, Griff didn't say anything anti-Semitic," Chuck insisted. "The real controversy there was: 'Why is this black man talking about something as intellectually challenging as Israel and Palestine? Go back to talking about the less consequential things rappers and DJs are supposed to talk about.'"

Of course, Chuck believes that popular hip-hop has gone back to being inconsequential: "I just don't believe that any of these cats believe in what they're spitting about anymore."

Which led him to Minneapolis again. He is a fan of Rhymesayers co-founder Slug's work in Atmosphere ("just a true original") and he heaped praise on another of the label's stars, Brother Ali.

"Now there's a guy you can tell believes in what he's saying 150 percent," he said of Ali, who got Chuck to guest on his "Us" album and repaid the favor by appearing on one of the new PE records. "He has a voice like Ray Charles. It's authentic, and you know it when you hear it. It's full of conviction and passion."

Those qualities still define Public Enemy, too, as heard on both of the new albums, "Most of My Heroes Still Don't Appear on No Stamps" and "The Evil Empire of Everything." Chuck's and Flavor's distinctive rapping styles are unchanged, but the themes reflect current issues, and the production has gotten a reboot. You'd be surprised how much sonic punch these records deliver.

They're the group's first full-length releases in five years. During that time Flavor Flav became a reality-TV series star, a fried-chicken restaurant owner and something of a punch line -- none of which caught Chuck by surprise.

"He has always been somebody to look at and wonder," he said with a laugh. "We've been through so much over the years, none of that had any effect on our relationship."

Just the thought of Public Enemy remaining an active group reflects something missing in today's hip-hop, he said.

"That's one thing that has spoiled rap as an art form, I think, is everybody only doing it by themselves and for themselves," he said. "You can't replace the chemistry that comes from being in a group.

"One-on-one, there are a lot of other rappers who are better than me. When I'm with my group, though, no one can touch me."
